Take down.
It is about as inaccurate as they come, and in the event it hits it doesn't do anything unusual. I would expect an inaccurate move to be high risk/high reward. It could miss, but if it hits it deals 100+ damage like High Jump Kick, Mega Horn, maybe some nasty side effects on top of it like Aero Blast or Fire Blast. All of the above have as good or better accuracy than take down.
There is no incentive to use this move. It is just a normal type move that deals average damage. If the accuracy issues and modest damage weren't deterrent enough, you receive a recoil too. If you want a normal type move and are content hurting yourself then just use Double Edge, it at least does much more damage and won't miss at least.
